SOFTWOOD CODE OF PRACTICE All TTF Members dealing in softwood and associated products are required to adopt and comply with this Code of Practice for use as a public and promotional document forming an integral part of the TTF Code of Conduct.
Its aim is to assist Members in the promotion of their company’s efforts to correctly supply accurately marked and labelled products and to ensure the exposure of those known to be breaching the Code as a result of wilful product mis-labelling or mis-marking.
This Code will apply to all softwood products of any dimension and is binding to all TTF Members dealing in such goods.
1.
Every effort will be made to ensure that products supplied will be correctly marked. Pack markings must correctly and accurately represent the timber which they contain, in terms of quality, dimension or structural grade. End stamps where they are applied should reflect the shippers normal published marking scheme.
2.
Structural grade stamps where applied must comply with the marking requirements of BS EN 518 for Visual Grading, and BS EN 519 for Machine Grading, until such time as they are superseded by the marking requirements of the harmonised standard
www.ttf.co.uk 5. 4. 3.
Where products are offered as made to BS or BS EN standards, or the recognized standards of other producing nations, Members will ensure that all the specification requirements of these standards are adhered to. In instances where no contractual reference is made to any specified standard, or specific agreement between the parties, the dimensional tolerances of the product will be as per BS EN 336 for Structural Softwood, BS EN 1313, Part 1, for Sawn and Processed Softwoods, and BS 1297 for Tongue and Groove Softwood Flooring. Furthermore, where preservative treatments are required, Members shall adhere to the guidance provided within the Code of Practice BS 8417 for the choice, use and application of wood preservatives.
No Member shall require any producer or seller to supply any product deliberately mis-marked or unmarked, which may give a false impression of the grade, dimension, structural grade or origin of the goods in question.
No Member will mis-describe any softwood product offered for sale, in terms of dimension, quality or structural grade. This includes where structural timber is supplied that all reasonable efforts are made to identify constructional end uses and to ensure in such circumstances the material supplied complies with the moisture content requirements laid down in BS 4978 for Visual Strength Grading and the UK National Annex of BS EN 519 for Machine Strength Grading, until such time as this latter Standard is replaced by the harmonised standard EN 14081.

EN 14081. This should include the application of a Wet or Dry mark to correctly represent the moisture content at the time when the Strength Grading took place and the stamp was applied. These requirements shall be incorporated in all supply contracts.
